About this map

Glacial prairie potholes and marshy depressions define this landscape in Edmunds County, reflecting the characteristic geography of the Missouri Coteau. The land is organized by the Public Land Survey System, with township and range lines like t121n r72w and t121n r71w providing the underlying grid for the region's agricultural development. Settlement is sparse, focused around a rectilinear network of rural roads such as Co Rd 5 and 337th Ave that facilitate access to isolated farmsteads.

Local history is anchored by the Old Saint John Church Cem, which stands as a quiet marker of the community's early social and religious foundations. The map reveals a high density of seasonal wetlands and small basins, illustrating why this part of South Dakota remains a critical area for water drainage and migratory habitats, even as contemporary thoroughfares like 140th St and 147th St traverse the township.
